Answer:
G'(1, 3)
Step-by-step explanation:
Counterclockwise rotation 90°: (x, y) ⇒ (-y, x)
So the point G is transformed to ...
... G(3, -1) ⇒ G'(1, 3)
Answer:
It's C
Step-by-step explanation:
Ex. y = 9x
x = 2
y = 18

Answer:
The graph shows the solution of the inequality y >
x - 2 ⇒ D
Step-by-step explanation:
In the inequality,
- If the sign of inequality is ≤ or ≥, then the line that represents it must be a solid line
- If the sign of inequality is < or >, then the line that represents it must be a dashed line
- If the sign of inequality is > or ≥, then the shaded area must be over the line
- If the sign of inequality is < or ≤, then the shaded area must be under the line
From the given graph
∵ The slope of the line =
=
=
= 
∵ The y-intercept is (0, -2)
∵ The line is dashed and the shaded area is over the line
→ By using the 2nd and 3rd notes above, the line is dashed and
the sign of inequality is >
∴ The inequality is y >
x - 2
∴ The graph shows the solution of the inequality y >
x - 2
